The insulating layer 150 includes a first sub-insulating layer 151, asecond sub-insulating layer 152, and a third sub-insulating layer 153.The first sub-insulating layer 151 is disposed between the substrate 110and the semiconductor layer 161, flattens/planarizes the surface of thesubstrate 110, and prevents moisture from permeating from the substrate110 toward the semiconductor layer 161. The second sub-insulating layer152 covers the semiconductor layer 161 and prevents a short circuitbetween the semiconductor layer 161 and the gate electrode 162. Thethird sub-insulating layer 153 covers the gate electrode 162 andprevents a short circuit between the gate electrode 162 and the sourceelectrode 163 and prevents a short circuit between the gate electrode162 and the drain electrode 164.

The organic light emitting element 140 includes a first electrode 141connected to the drain electrode 164 of the thin film transistor 160, anorganic emission layer 142 disposed on the first electrode 141, and asecond electrode 143 disposed on the organic emission layer 142. One ofthe first electrode 141 and the second electrode 143 is an anode as ahole injection electrode, and the other is a cathode as an electroninjection electrode. The first electrode 141 is disposed one by one foreach pixel, and the second electrode 143 is disposed throughout theentire display area DA.

Light emitted from the organic emission layer 142 may be transmittedthrough the first electrode 141 and the substrate 110, or may betransmitted through the second electrode 143 and the thin filmencapsulation 130. In the former, the substrate 110 is disposed closerto the window 20 than is the thin film encapsulation 130 (referring toFIG. 1), while in the latter, the thin film encapsulation 130 isdisposed closer to the window 20 than is the substrate 110 (referring toFIG. 1). In FIG. 3, element number 154 indicates a planarization layercovering the source electrode 163 and the drain electrode 164, andelement number 155 indicates a pixel definition layer defining aformation region of the organic emission layer 142.

For example, incident external light is linearly-polarized by the linearpolarization layer and is circularly-polarized, in one direction, whilepassing through the ¼ wavelength layer (quarter-wave plate). Therotation direction is reversed while the circular polarized light isreflected by the metal layers of the display unit 120, and the circularpolarized light is converted to linearly polarized light while passingthrough the ¼ wavelength layer (quarter-wave plate). A vibrationdirection of the linearly polarized light is perpendicular to atransmissive axis of the linear polarization layer such that thelinearly polarized light does not pass through the linear polarizationlayer.

The antenna sheet 30 to receive and transmit a wireless signal isdisposed on the polarization film 40. A size of the antenna sheet 30 maybe larger than the size of the display area DA, and may be equal to orsmaller than the size of the display panel 10. A first adhesive layer 61may be disposed between the antenna sheet 30 and the polarization film40.

The antenna sheet 30 may have a pair oflong sides 301 and a pair of short sides 302, and the first directionDR1 and the second direction DR2 may be diagonal directions of theantenna sheet 30 crossing both of the long side 301 and the short side302.

The first antenna portion 33 includes a plurality of openings OP. Theplurality of openings OP are respectively disposed between two adjacentfirst metal lines 331 and between two adjacent second metal lines 332.In the entire first antenna portion 33, the plurality of opening OP mayhave the same size and may be uniformly disposed.

For example, the plurality of first metal lines 331 and the plurality ofsecond metal lines 332 may have the same width. Also, the plurality offirst metal lines 331 may be aligned with a predetermined distancebetween each other, and the plurality of second metal lines 332 may bealigned with a predetermined distance between each other. Further, adistance between two adjacent first metal lines 331 may be the same as adistance between two adjacent second metal lines 332.

The plurality of first metal lines 331 and the plurality of second metallines 332 may have a width of about 2 μm to 3 μm, respectively. The sizeof the plurality of openings OP is larger than the size of one of pixelsprovided in the display unit 120, and a plurality of pixels are disposedto correspond to one opening OP.

The second antenna portion 34 is integrally connected with the firstantenna portion 33. For example, an end part of the plurality of firstmetal lines 331 and an end part of the plurality of second metal lines332 are integrally connected with an inner side surface of the secondantenna portion 34. The second antenna portion 34 has the frame shapecorresponding to the non-display area NDA of the display panel 10 anddoes not have openings thereby having a higher density than the firstantenna portion 33. The second antenna portion 34 reinforces theperformance of the first antenna portion 33, thereby increasing theperformance of the antenna sheet 30.

The antenna sheet 30 may include a resin layer 35 disposed between thebase material film 31 and the metal layer 32. The resin layer 35 mayinclude a recess portion with the same shape as the metal layer 32, andthe metal layer 32 may be disposed at the recess portion. The antennasheet 30 may be manufactured by a process that is described in detailbelow.

FIG. 5A to FIG. 5D are cross-sectional views showing a manufacturingprocess of an antenna sheet in a display device shown in FIG. 1. Themanufacturing process shown in FIG. 5A to FIG. 5D represents anexemplary embodiment of the present inventive concept, and the antennasheet may be manufactured in other ways.

Referring to FIG. 5A, a resin layer 35 is formed on a base material film31. The resin layer 35 may include an ultraviolet ray curing resin andmay be formed by a general coating method. Referring to FIG. 5B, animprint mold presses the resin layer 35 to form a recess portion 36 atan upper surface of the resin layer 35. The recess portion 36 has thesame shape as a metal layer that is previously designed.

Referring to FIG. 5C, a metal paste 37 is printed on the recess portion36 of the resin layer 35. The metal paste 37 includes metal particles ofsilver, copper, and/or aluminum, and organic materials. Referring toFIG. 5D, the resin layer 35 and the metal paste 37 are exposedultraviolet rays during a thermal treatment. The resin layer 35 is curedhard by the ultraviolet rays and the organic materials included in themetal paste are removed by the thermal treatment, thereby completing ametal layer 32. A thickness of the metal layer 32 may be smaller than adepth of the recess portion 36.

When the resin layer 35 includes the recess portion 36 and the metallayer 32 is disposed at the recess portion 36, spreading of the metalpaste 37 may be prevented in the manufacturing process of the antennasheet 30. Accordingly, in the first antenna portion 33, a plurality offirst metal lines 331 and a plurality of second metal lines 332 maymaintain an intended minute line width. When the antenna sheet 30includes the resin layer 35, the opening OP of the first antenna portion33 is filled with the resin layer 35.

Again, referring to FIG. 1 and FIG. 2, the antenna sheet 30 may furtherinclude an access member 38 fixed to the second antenna portion 34. Theaccess member 38 is electrically connected to a controller. A touchpanel 50 is disposed on the antenna sheet 30.

The touch sensor may be operated by various methods, for example,the touch sensor may be of a capacitive type for sensing a positionwhere a capacitance change is generated depending on the point ofcontact. The touch panel 50 may have various structures.

The window 20 is disposed on the touch panel 50. The window 20 isdisposed at a highest part of the display device 100 to protect thetouch panel 50 and the display panel 1 from an impact or externalinterference. A third adhesive layer 63 may be disposed between thetouch panel 50 and the window 20.

The window 20 may include a transparent substrate 21 and a lightblocking film 22 disposed directly under the transparent substrate 21and corresponding to the non-display area NDA of the display panel 10.Among the transparent substrate 21, a part that does not overlap thelight blocking film 22 is a light transmission region, and a partoverlapping the light blocking film 22 is a light blocking region. Thelight blocking film 22 prevents the non-display area NDA of the displaypanel 10 from being seen by the user.

The display device 100 of the above-described approach includes theantenna sheet 30 overlapping the display panel 10. Accordingly, theelectronic device including the display device 100, for example, themobile electronic device, may do without a separate antenna that isdisposed outside the display device 100 such that the entire structuremay be simplified and the entire thickness may be minimized.

For example, the window 20 is made of the transparent substrate, and theantenna sheet 30 is in contact with a lower surface of the transparentsubstrate. Among the window 20, the part overlapping the first antennaportion 33 becomes the light transmission region, and the partoverlapping the second antenna portion 34 becomes the light blockingregion. The second antenna portion 34 does not transmit the light,thereby preventing the non-display area NDA of the display panel 10 frombeing recognized at the side of the user.

The touch panel 50 may be disposed on the polarization film 40, and afourth adhesive layer 64 may be disposed between the polarization film40 and the touch panel 50.
